Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of stress and
anxiety related symptoms is more but as you are in post menopausal age (53 years), better to first rule out heart diseases.
Post menopausal women are at increased risk of heart diseases because of low
estrogen and
progesterone.
So get done ecg and 2d echo first.
If both these are normal then no need to worry for heart diseases.
Stress and anxiety related symptoms is more likely.
So
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on it's solution.
You may need newer anxiolytic drugs too. Don't worry, you will be alright. But first rule out heart diseases,
Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
